Aging is a highly complicated phenomenon. It affects every person, yet the rate and the extent of the aging process of each individual vary. There are some older adults who, despite their advanced age, are healthy, independent and mentally and physically functional and who continue to be active members in their community. On the other hand, other older adults are suffering from chronic illnesses, neurodegenerative diseases and various incapacities that render them non-autonomous and dependent upon other people, and which not infrequently drive them in social isolation. Inadvertently, the study of factors contributing to the aging process plays a key role in the deeper understanding of aging. Understanding of the behavioral factors that affect aging, such as dietary habits, smoking and physical activity, and the socio-economic status, family relationships and education, may be of even greater importance, since some of these factors are malleable and can be modified. As an example, many studies have documented the beneficial role of calorie deficient and anti-oxidant rich diets in promoting a long and healthy lifespan. Other studies have highlighted the role of smoking as an accelerator of aging, while others stress the role of physical activity as a potential aging decelerator. Higher socio-economic status is accompanied by better quality of life and working conditions, while family relationships can have both a positive and a negative impact on aging. It appears that more years of education ensure better cognitive function in advanced age. At the population level, public health interventions aimed at enhancing those factors which are beneficial may play a pivotal role in designing healthy aging for future generations.
